FILTER.

SPECIFICATION forming part of Letters Patent No. 451,060, dated April28, 1891.

Application filed June 23, 1890. Serial No. 356,407. (No model.)

To (on whom it may concern.-

Beit known that I, JOHN F. LE BEAU, a citizen of the United States,residing at Toledo, Ohio, have invented certain new and usefulImprovements in Filters, of which the following is a specification.

My invention relates to that class of filters in which the waterpercolates both upward and downward; and its object is to provide afilter which shall be cheap, simple, durable, and effective, and moreparticularly to utilize the legs or standards which support the body ofthe filter as filtering-conduits. I attain these objects by means of themechanism hereinafter described, and shown in the accompanying drawings,made part hereof, in which- Figure l is a side elevation of my filter;Fig. 2, a central vertical section on line y 1 Fig. 3; Fig. 3, asectional plan view on line 00 m, Fig. l; and Fig. 4, a sectional planview on line .2, Fig. 1.

Like letters indicate like parts in all the views.

A is the body of the filter, which for convenience I prefer to makecylindrical in form. The body of the cylinder is divided into twocompartn1entsone e for the impure water, the other f for the filteredwater-the partition between the two compartments being marked B. Thebody of the filter A is provided with the usual cap or cover O, and issupported upon four hollow legs or standards (I, (1, (Z and d These legsor standards are made, preferably, of heavy sheet metal, and terminateat bottom in and are rigidly secured to base-plate g. Each of the legsis is filled with filtering material-such as charcoal, gravel, and the1ike-resting on perforated plates 0, fixed near the bottom of each ofthe hollow standards. Leg or standard at is provided at its top with aperforated cap, through which water enters from chamber 6, and at bottomwith a sponge-box h, (see Fig. 2,) provided with a screw-cap h, by meansof which the sponge may be readily withdrawn, cleansed, and inserted inplace. Around this sponge-box is a sediment-chamber h from which,through horizontal pipe twater passes to leg or standard d, thenceupward through this leg or standard until it reaches horizontal pipe 01,thence over through pipe 1" to leg (1 thence downward through leg orstandard (1 into sediment-chamber 7c, thence into leg or standard dthrough horizontal pipe t thence upward through-leg or standard (P, andout through perforated plate at top of the last-mentioned leg orstandard into the pure-water chamber f, from whence it may be drawnthrough cock or spigot Z. Thus it willbe seen the course of the waterfrom the impurewater chamber 6 into the pure-water chamberf is asfollows: downward from chamber e through standard d, through sponge-boxh, sediment-chamber 7%, horizontal pipe 2', up through standard d, overthrough horizontal pipe 1', downward through standard d int-osediment-chamber 7c, over through horizontal pipe 1 and thence up andout into the purewater chamber f through standard (1 the four legs andtheir connecting-pipes thus forming a continuous conduit from chambereto chamber f. Standards d and d are also provided withsediment-chambers at bottom, (not shown in the drawings,) thesediment-chamber in each of the standards being directly beneathperforated plate 0. Each of the four legs of the standards is providedat bottom with screw-caps, by means of which the sedimentchambers arereadily emptied and cleansed. Standards (1' and d are provided withscrewcaps at their top. By removing the last-mentioned screw-caps andthe perforated plates above referred to and inverting the filter thefiltering material may be readily removed, and through the same openingsthe filter may be conveniently repacked. The water in its course abovedescribed enters the various sediment-chambers by percolation Withoutdisturbing the sediment, and'the sediment which accumulates in thesediment-chambers is not disturbed by pouring water into theimpure-water chamber or withdrawing water through spigot Z.

Around the body of the filter I provide an outer jacket a, between whichand the body of the filter is an annular space a, closed at bottom. Theair-jacket thus formed serves as a non-conductor of heat, andthe waterwithin the filter is thereby kept cool.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, is

A filter having the body thereof divided into two chambers and supportedupon four covering the inlet and outlet of said filteringhollow legsconnected and adapted to form a conduit, and screw-caps closing theupper IO continuous filtering-conduit leading; from one ends of legs dand (5 substantially as shown to the other of said chambers, each ofsaid and described, for the purpose specified.
